You could get a calcium and adjusted calcium. They do a calculation to adjust for the amount of albumin you have in your blood. You need a DEXA scan to see how much is in your bones. I did not take calcium for years because when I was first diagnosed my calcium would be close to 11. Now it has been hovering about 9.4 so I feel pretty comfortable taking a calcium supplement. I eat a pretty healthy diet but not dairy or fortified foods…mostly leafy greens, almonds, and seeds. Some beans and lentils. I’d start with how much calcium you have and then decide on supplements. You could take 500-600 mg.
